SHIPPING-BECEPTACLE.

Specification of Letters Patent.

Patented June 26,1917.

Application filed September 29, 1916. Serial No. 122,856.

To all whom it may concern:

Be it known that I, CHARLES B. SMITH, a

citizen of the United States, residing at T- ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Shipping-Receptacles, of

which the following is a specification.

The invention relates to receptacles, such as pails, buckets, drums, and the like, used for shipping products, generally dry products, though they may contain liquids, and involves certain improvements on the invention disclosed in Letters Patent issued to me on January 12, 1915, No. 1,124,669, and the improvement may be embodied in receptacles differently constructed.

One object of the present invention is the substitution for the ordinary lapped joint at the ends of the blank forming the body of the receptacle of a secure and satisfactory butt joint or seam which will prevent the passage therethrough not only of powdered and granulated materials, but also of liquids.

Another object is the provision of a metallic bottom of simple and strong construction. x

The invention consists in certain novelties of construction and combinations of parts as herein set forth and claimed.

When the drumor pail or bucket has a body formed by a blank of yielding fibrous material the butt joint uniting the edges should be rigid and means be provided for preventing the contents of the receptacle sifting or leakin to the outside. The bottom should also fie rigid and strong enough to withstand blows such as are frequent in shipping. The body portion, however, should be made so that it will bend and spring back to normal position when subjected to blows to which such receptacles are commonly subjected. With a rigid bottom, top and butt joint the body portion may be of relatively thin fiber and the Weight of the receptacle limited without decreasing the strength of the whole. 7

The accompanying a drawing illustrates two examples of the embodiment of the improvements constructed according to the best modes of procedure I have so far de-' vised for the purpose.

Figure 1 is a perspective view of a shipping drum of fiber embodylng theimprovements. Y

'tiveto the surface of the clamp.

Fig. 2 is a section of part of a similar but tapering drum or pail, the vertical section being taken on the line of the joint showing one edge of the blank and through part of the bottom, and through part of the cover, also showing part of the inner surface.

Fig. 3 is a view in perspective of the metallic clamp or bar which unites the edges of the blank.

Fig. 4 is an enlarged section of Fig. 1 or .Fig. 2 on line 4-4, showing the butt joint.

The main body part A of the receptacle is of fibrous material, such as paper board or the like, and is formed by cutting to shape a blank and bendin it so that the free vertical edges B B wil be in contact or abut. The edges are rigidly united by a slightly concavo-convex metallic clamp C having projecting or bent edges D D and two series of prongs E E cut from and struck up to substantially right angular position 1&1}?-

e prongs are forced through the fiber, one series of prongs being located each side of the meeting edges of the blank, and the points '8 are then turned down into the material on the inner surface. The pressure should be sufficient to force the edges of the clamp into close frictional contact with the outer surface ofthe material so there will be no opening for any materialor liquid which might pass the abutting edges of the clamp.

This makes a very strong and rigid butt joint. There is also a saving of some two inches of fiber on each end of the blank, and at the same time the clamp can easily and quickly be applied and the first cost reduced.

The bottom F is struck up from a blank of thin metal to form a circular recess Gr inner flange L of the bottom and the edge j H of the reinforcing strip or disk is passed a series of rivets M to holdthe parts rigidly united. It will be noted that by this combination a strong, rigid double bottom is provided entirely closed without any opening for the passage of either granulated material or liquid. When the receptacle is to be used as a liquid container the inner surface is, of course, treated with a suitable compound in any well known Way.

A shipping receptacle as shown and described is of light weight, has-a strong, rigid bottom and top and the body between is of a yielding material which can bend and sprin back to normal position without 'breaklng, and the same as a whole constitutes a superior means for the uses intended.

What I claim is:

The combination in a shipping receptacle having a body formed from a blank of fibrous material With the edges abutting each other, of a metallic clamp, the length thereof being greater than the width, provided with two series of prongs struck from the body of the metal and the longitudinal free .edges outside the series of prongs slightly outer surface of .the material, whereby a 25 closed joint is formed.

In testimony whereof I aflix my signature.

CHARLES B. SMITH.
